Vi/TASTE MECHANISM.

Original application filed May 5, 1920, Serial No. 378,395. Dividednndthis application filed February 3, 1923.

To all whom it may concern:

Beit known that 1, Enwanp F. Ninn ion zn, a citizen of the United States, residing, at Milwaukee, in the county of Milwaukee and State of l/Visconsin, have invented certain new and useful Improvements in Waste Mechanism, of which the following, is a specification, reference being. had to the ac ce mpanying drawing, forming a part there- 0 V This invention relates to wasteinechanism for bath tubs and similar receptacles and the object of the invention isto improve the con struction and operation of waste mechanism in the manner to be hereinafter described and claimed, this application being a division of my prior application for Letters Patent for improvements in waste mechanism, filed May 5, 1920, Serial Number 37 8,995.

Referring to the drawings which accompany this specification and form a part hereof, which drawings illustrate an embodiment of this invention, and on which drawings the same reference characters an used to designate the same parts in each of the views, Fig. 1 is a vertical section of the waste mechanism, parts being shown in elevation; and Fig. 2 is a vertical sect-ion taken on the line 2-2 on Fig. 1, looking in the direction indicated by the arrows.

Referring to the drawings, the reference numeral 1 designates a bath tub, or liquid receptacle, which is provided with an outlet aperture 2 and an overflow aperture 3. A pipe connection 4, which is provided with a flange 5, is screwed into the elbow 6 and a packing 7 makes a fluid tight joint. The elbow 6 is connected with the stand pipe 8 in line with a tubular valve 9. The valve 9 has an upper, circumferential valve face 10 and a lower, circumferential valve face 11. The upper valve face 10 projects beyond the body of the valve and the lower valve face 11 is arranged within the circumference of the body of the valve so that the valve may be readily assembled or disassembled. Inwardly projecting valve seats 12 and 13 are provided for the valve faces 10 and 11. It will be readily seen from an inspection of Fig. 1 of the drawings that, with this construction when the valve 9 is closed, fluid cannot escape from the receptacle 1 either up or dow n past the valve 9 while fluld overfiowlng 1s free to pass through the valve 9. The valve Serial No. 616,718.

ody. 14 s re ab y p v e it as id or steady flange or rib 1 5 which is located opposite the elbow 6 to against dis placement or binding of the valve 9 when the valve is partlyopened and fluid is'ru nningto waste through the elbow 6. The tubular body 16;.of the valve 9;rnakes a sub stantially close fit within the valve seat12 t m p fluid from rising past the valvev 9 and fouling the interior of thestand pipei8. and-the parts at the lower end thereof. This construction makesthe mechanism sanitary and reliable. The valveseat 12j serves as a scraper'to remove deposits on the exterior of the valve 9 and, as it is very short vertically, there is no opportunity for soap, for example, to work in between the valve and the seat and produce corrosion, sticking and wear.

The valve 9 can be raised and lowered in any suitable manner. The drawings illustrate a knob 17 connected with the valve and studs 18 and 19 projecting into inclined grooves in a member at the top of the stand pipe so that the valve can be opened and closed and can be held open in a common and welhknown manner.

One of the difficulties heretofore encountered in installing bath tub Wastes has been due to the difi'erent inclinations of the ends of bath tubs in which the overflow apertures were located. I overcome the difliculty by using an overflow pipe 20 which projects into a pipe connection or nipple 21 on the stand pipe 8 and which is made smaller than the interior of the nipple so that it can be turned out of direct line with the nipple. A packing 22 makes a fluid tight joint and the follower 23 is bored larger than the pipe 20. The pipe 20 is provided with a flange 24 to seat against the bath tub, and the joint is made tight by a packing 25. A rod 26 is screwthreaded at both ends and is screwed into a nut 27, passes through the grating 28 and is provided with a nut 29 on its end bearing against the grating. The nut 27 is movable within the nipple 21 so that the rod 26 can assume different angles. The drawings illustrate the nut 27 as pivoted on pivot screws 30 and 31, which are screwed into the nipple 21 and engage with recesses in the nut 27.

The advantages of the invention are of great importance from practical and sanitary standpoints. One standard overflow fitting can be properly and eflectively secured to bath tubs, or receptacles, the inclinations of the ends of which vary.

The valve body 14; is provided with the waste inlet 32 and the stand pipe 8 is provided with the overflow inlet 33 above the waste inlet 32. The stand pipe 8 and the waste pipes 34 and 35 are illustrated by the drawings as connected with the valvebody 14 by means of slip joint connections to illustrate a practical and convenient method of making pipe connections.

What I claim is:

1. In waste mechanism,the combination with an overflow nipple of an overflow pipe of smaller size than the nipple, means to make a tight joint between the overflow pipe and the nipple, and means movable with respect to the nipple to connect the nipple and the overflow pipe to a receptacle.

2. In waste mechanism, the combination with an overflow nipple of an overflow pipe of smaller size than the nipple, means to make a tight joint between the overflow pipe and the nipple, and a rod movably connected with the nipple to secure the nipple and the overflow pipe to a receptacle.

3. In waste mechanism, the combination with a pipe connection, an overflow pipe connected to said connection, and a rod arranged in said connection and said pipe to connect the same to a receptacle, of a member secured to an end of said rod and pivotally connected to said connection.

l. In waste mechanism, the combination with a pipe connection, an overflow pipe connected to said connection, and a rod arranged in said connection and said pipe to connect the same to a receptacle, of a nut threaded upon an end of said rod, and screws passing through said connection into opposite sides of said nut whereby the latter ispivotally connected to said connection.

In witness whereof I hereto afiix my signature.
